Bellow with Solid liner

Bellow with Solid Liner – Thermal Compensator for Exhaust Manifolds

The bellow with solid liner is a precision-engineered component designed to manage thermal expansion in the most demanding sections of the exhaust system. Its primary function is to compensate axial and angular movement caused by heat fluctuations, particularly in exhaust manifolds and turbocharger outlets.

This component is manufactured from AISI 321 stainless steel, a titanium-stabilized alloy known for its excellent resistance to high temperatures, thermal fatigue, and scaling. It performs reliably under continuous heat cycling, pressure pulsations, and critical sealing requirements.

While the primary function of this bellow is thermal compensation, it also contributes to vibration absorption within the system. However, unlike conventional flex pipes designed specifically for engine movement and noise damping, this component is optimized for dimensional stability in rigid exhaust layouts subjected to extreme heat and pressure.

The integrated solid inner liner protects the inner structure from direct exhaust gas impact. It ensures stable flow conditions, reduces turbulence, and minimizes wear – resulting in longer service life and dependable operation in high-load environments.
